IBOC -- a way to jam skywave signals from Mexico and Canada at night, just
like the USSR did with VOA, RFE/RL, ...

The US AM band is so heavily overallocated already to meet the classical
cold war definition of jamming, with respect to being able to hear stations
in Canada during nighttime hours (no Canadian station operates at 50 kW at
night that I am aware of).


There are plenty of Canadian stations that run at 50kW. CKLW in Windsor, for one.
CBU in Vancouver, as well as CBC stations in Regina and Winnepeg, too (although
they've divested themselves of the 740 and 940 kHz operations in Toronto and
Montreal). There are still quite a few Canadian Clears, although some of those
channels, like 800kHz, are shared with Mexico, and thus run lower power or
directional patterns at night.
